We broke down in San Antonio, with a loaded trailer and found Bull One Diesel repair. Bull, the owner is extremely knowledgeable and the technician that worked on our truck stayed late to get us back on the road. We highly recommend Bull One.

Excellent service. Professional friendly staff. Bull definitely went the extra mile for me.

Professional, easy to talk to. Bull went over details he felt needed attention with my brakes. Had efs checks on hand.

When you're looking for a Big Truck Mechanic Shop that's honest, respectful, and trustworthy, "Bull-One Diesel" is the place I highly recommend if you want to keep your wheels rolling! But as human beings we are, anyone can make a mistake or two but Bull-One will not only take care of the problem should that be the case but makes sure that the customer is completely satisfied!! Bull's got lots of knowledge in both Technical and Retro.

Honest mechanics. They get the job done and do it right. The owner "bull" he is definately a kool person. He knows what he's talking bout. If He doesn't know what the problem is he'll find out for you. Prices are fair. Workers know what they're doing. All in all a recommend location for anyone who has a freightliner with a dd15 engine, or to anyone in general!!!!

Great place for diesel work. Have been going there for years. Would definitely recommend this place.

It's been a 2 years since they rebuilt my N14 , still running like a champ , highly recommend ...
